What is Keyflow?
Keyflow is a free, searchable reference for the things you look up while you work.

It also has free tools: an MCP config generator for Claude Desktop, Cursor and Claude Code, a cron expression explainer and a UTM builder. No sign-up, no ads.

Online Music Visualizer is an in-browser studio designed for independent artists and producers to create audio-reactive music visualizer videos without a steep learning curve or a traditional video editor. It supports importing audio and artwork, applying audio-reactive presets, and previewing changes in real time before exporting. The goal is to provide a predictable, browser-based workflow that keeps local assets private and avoids ongoing subscription costs.
